(-)-Epigallocatechin gallate Chemische Eigenschaften,Einsatz,Produktion Methoden
Chemische Eigenschaften
solid
Verwenden
(-)-Epigallocatechin Gallate is a tumor-inhibiting constituent of green tea. (-)-Epigallocatechin Gallate alters the cleavage of amyloid precursor protein, decreasing production of amaloid-β and amaloid plaques in mice. This compound has neuroprotective properties.
Allgemeine Beschreibung
Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
Epigallocatechin gallate is a potent polyphenolic flavonoid which is found as a component of tea. It exhibits antioxidant, antimutagenic, antitumor and anti-inflammatory properties, thereby contributing to the health-beneficial actions. It finds potential use as a drug candidate in the pharmaceutical, cosmetic, and nutritional fields.
Hazard
Moderately toxic by ingestion.
Anticancer Research
EGCG and EGC are the active polyphenol compounds found in green tea, found toinhibit p-glycoprotein transport activities in Chinese hamster ovary (p-gp+) cells.EGCG facilitates the retraction of MDR phenotype by reducing cellular drug effluxwhen given in combination with vinblastine or doxorubicin. Hesperetin, quercetin,daidzein, silymarin, naringenin, and resveratrol also inhibit the MRP1, MRP4, andMRP5 (Kawasaki et al. 2008). Curcumin increases the cellular accumulation ofanticancer agents like cisplatin, tamoxifen, daunorubicin, vincristine, anddoxorubicin and thereby effectively sensitizes the drug-resistant cancer cells. Areduction in MDR1B expression in L1210/Adr cells (mouse leukemic MDR cells)by curcumin is mediated by PI3K, Akt, and NF-κB pathways. It also inhibits theABCG2 transporter activity. In addition curcumin facilitates the accumulation ofmitoxantrone and doxorubicin in ABCG2-expressing HEK cells and hence reversesMDR (Kawasaki et al. 2008; Dandawate et al. 2013).
